Migration to Godot 4.0

[daveTheOldCoder]

I successfully migrated this plugin to Godot 4.0. I'm posting the changes to the two files radial_progress.gd and RadialProgressBar.gd below, in diff format.

If you're not familiar with diff format: The lines in the Godot 3 files are prefixed with <, and the lines in the Godot 4 files are prefixed with >.

diff -r radial_progress.gd.3 radial_progress.gd.4

With the changes noted above, this plugin works correctly in Godot 4.2-dev5.
